Radar Imaging Could Be the Key to Monitoring Climate Change

Cars That Think

As a child, Alberto Moreira discovered his passion for electronics from the kits for exploring science, technology, engineering, and mathematics that his father bought him every month. Moreira’s technology also helps to track the effects of climate change. Picard Medal for Radar Technologies and Applications.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

Another concern is whether the inclusion of offsets would send the appropriate price signal to encourage the development of long-term mitigation technologies. From a global climate change perspective, it does not matter where or from what source the reduction occurs: the effect on the atmospheric concentration of GHGs would be the same.
